Ice Man still a source of research

At www.eurekalert.org/pub_releases/2018-06/p-stf061318.php … continuing study of the ice amn found in a melting glacier in the Alps a few years ago has found a different dimension to write about – his use of stone tools. The ice man dates back to around 3200BC (although now backdated by IntCal2013 a bit earlier). His stone tools were made of chert – a form of flint. It seems they originate from different locations in what is now the Trentino region of Italy. For the full paper go to http://journals.plos.org/plosone/article?id=10.1371/journal.pone.0198292
